Summary:

Description
  • Radiopaedia case ID: 47260
  • Image ID: 24447729
  • Image stack position: 5/15
  • Plane projection: Sagittal
  • Aux modality: T1
  • Study description: MRI Cervical Spine
  • Study findings: The vertebral bodies have normal height and alignment. Nonunion of the C1 posterior arch on the right (more conspicuous on CT) is consistent with an anatomical variant. There is degenerative ankylosis of C4 and C5 vertebral bodies associated with MODIC 2 signal changes of their interposed endplates. No bone marrow edema, facet joint effusion or abnormal disc signal. Anterior to the C4-C6 vertebral body there is a thin layer of prevertebral high signal however this is not associated with evidence of anterior longitudinal ligament or disc disruption. The posterior longitudinal ligament and ligamentum flavum appear intact. No posterior soft tissue bruising or hematoma. No epidural abscess. Bulky osteophytes/ossification of the posterior longitudinal ligament from C4 to C6/7 is eccentric to the right. This causes severe canal stenosis and cord compression posterior to C5 and C5/6; associated cord edema extends between C4/5 and C6/7. Disc osteophyte complex at C4/5 impinges upon the passing right ventral nerve root and causes moderate right and mild left foraminal stenosis. At C5-6 the eccentricOPLL/osteophytosis impinges the pre-foraminal right C6 nerve root, and left uncovertebral osteophytes cause moderate left foraminal narrowing. At C6-7, there is mild indentation of the thecal sac by right paracentral protrusion without cord contact or foraminal stenosis.
